Definitions

  • the disclosure relates in general to locks, and more particularly, to a core lock that is configured to provide electronic locking and unlocking of a lock. While not limited thereto, such a lock is well suited for use in association with furniture and cabinets, including as a retrofit to existing furniture and cabinets. Of course, the lock is not limited to such use or to such a field of use, and the foregoing is solely for purposes of example.
  • locks that include a shell mounted on the door or cabinet, and an insertable and removable lock core that plugs into the shell.
  • the shell not only houses the core, but also attaches to a driver for accomplishing the locking and unlocking function when rotated.
  • the lock core acts to lock the driver in place when there is no key inserted in the lock core due to lock core tumblers that protrude into the shell to restrict the lock core and driver from rotation.
  • Such systems are ubiquitous, however, there are nevertheless drawbacks.
  • such systems typically have a vast number of different tumbler configurations, and corresponding keys associated with each such different tumbler configuration.
  • a supplier must include a relatively large supply of spare locks, tumblers and keys to match those that are out in the field.
  • the removal and replacement of such locks is very time consuming and labor intensive.
  • the disclosure is directed to a lock.
  • the lock includes a housing assembly, an actuatable lock assembly and a latching assembly.
  • the housing assembly defines a cavity.
  • the actuatable lock assembly is associated with the housing.
  • the actuatable lock assembly is positionable in at least a closed orientation and an open orientation.
  • the latching assembly further includes a latch, a cam and a motor.
  • the latch is positioned within the cavity of the housing assembly.
  • the latch is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation.
  • the latch has a cam profile.
  • the cam is rotatably mounted within the cavity of the housing assembly.
  • the cam has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position.
  • the motor is coupled to the cam. Actuation of the motor causes rotation of the cam, and, in turn, movement of the latch between the locked and the unlocked position.
  • the actuatable lock assembly further includes a knob movable relative to the housing assembly.
  • the knob is positionable between an open orientation and a closed orientation through at least one of rotating about an axis, translating in an up and down or right and left configuration, and movement inward and outward.
  • the knob rotates about an axis spaced apart from the latch.
  • the actuatable lock assembly further includes a notch positioned therealong.
  • the latch includes a portion selectively insertable into the notch when the latch is positioned in the locked position, thereby precluding movement of the actuatable lock assembly into the unlocked position.
  • the actuatable lock assembly further includes at least one ball and a biasing member, interfacing with the actuatable lock assembly.
  • the at least one ball and biasing member facilitating alignment of the actuatable lock assembly relative to the housing assembly.
  • the ball is associated with the actuatable lock assembly. The spring biasing the ball against the actuatable lock assembly and interfacing with the housing.
  • the latch is one of slidably and rotatable movable relative to the housing between a locked and unlocked position.
  • the latch is slidably movable relative to the housing along an axis that is perpendicular to an axis of rotation of the cam.
  • rotation of the motor in a first direction directs the latch toward the unlocked position. Additionally, rotation of the motor in a second direction directs the latch toward the locked position.
  • the latch further includes a second cam profile disposed thereon.
  • the cam further includes a second follower configured to engage the second cam profile.
  • the cam profile and the second cam profile are each substantially parallel to each other so as to define a longitudinal channel therebetween.
  • the cam further including a body having a first side and a second side.
  • the first follower extends from the first side of the body.
  • the second follower extends from the second side of the body.
  • the first follower interfaces with the cam profile.
  • the second follower interfaces with the second cam profile.
  • the body of the cam is positioned at least partially within the longitudinal channel.
  • the longitudinal channel defines an axis of slidable movement of the latch between the locked position and the unlocked position.
  • the cam profile includes a first slot, a second slot and a third slot.
  • a first ridge is defined between the first slot and the second slot.
  • a second ridge is defined between the second slot and the third slot.
  • a width of the second slot is at least as wide as the first follower.
  • the second follower further includes a first ramp and a second ramp, with a peak positioned therebetween, and the peak of the second follower substantially corresponds to the second slot of the first cam profile.
  • the housing assembly is attachable to one of the group consisting of doors, drawers, cabinets, pantries, desks, credenzas, cabinets and wardrobes.
  • the housing assembly may be directly attached to such structures or may be indirectly associated with such structures.
  • the housing assembly is not limited to attachment to such structures.
  • the cam upon actuation of the motor, from either the locked or the unlocked position, the cam rotates through an initial arcuate distance prior to imparting a force upon the cam follower to move the latch toward the other of the locked or unlocked position.
  • the lock further includes an electronic control assembly electrically coupled to the motor, configured to control the same, and an input device associated with the housing assembly.
  • the input device allows a user to provide an authorizing signal to the electronic control assembly to direct the motor to initiate rotation thereof.
  • the lock further includes a latch position sensor associated with the electronic control assembly.
  • the latch position sensor determines the position of the latch in at least one of the locked position and unlocked position.

  • the rotational blocker includes a first cam profile within a cavity of the blocker, and a lobe extending on an outer surface thereof. The lobe interfaces with the proximal end of the latch.
  • the cam 106 is positioned within the cavity of the blocker so that rotation of the motor interfaces the first follower of the cam with the first cam profile of the blocker.
  • the first cam follower freely rotates relative to the blocker until the first stop is reached.
  • continued rotation of the first cam follower rotates the blocker, as shown in FIG. 28B .
  • the rotation of the blocker eventually moves the blocker out of the way of the latch.
  • the latch is then free to slidably move within a latch channel.
  • the cam 106 is rotated in the opposite direction relative to the blocker until the second stop is reached.
  • the continued rotation of the cam by the motor rotates the blocker, returning the blocker into a position that interfaces with the proximal end of the latch.
  • the blocker precludes slidable movement, which, in turn, precludes rotation of the knob that interfaces with the distal end of the latch.
  • the blocker function and the latch function can be integrated into a single element. That is, the distal end of the latch can be configured to include the first cam profile and the second cam profile that was on the blocker.
  • the cam profiles are in the direction of translation of the latch, as opposed to being perpendicular thereto in the other embodiments.
  • the cam and the motor are rotated so that the cam can interface with the first and second cam profiles. In turn, actuation of the motor directly moves the latch.
